sgunhouse writes "Wired is running an article on a Supreme Court challenge (well, actually two of them) to the use of drug-sniffing dogs. The first case discussed involved Florida police using a drug-sniffing dog as a basis for searching a suspected drug dealer's home. The court in Florida excluded the evidence obtained from the search, saying a warrant should be required for that sort of use of a dog. Personally, I agree — police have no right to parade a dog around on private property on a 'fishing expedition', same as they need a warrant to use a thermal imaging device to search for grow houses. I have no use for recreational drugs, but they had better have a warrant if they want to bring a dog onto my property."
